Online AutoML: Evaluating Poisoning Attacks on Adversarial Training Defense Strategy in IoT Networks

Read the original on Hugging Face Trending Papers →

The paper investigates how poisoning attacks—specifically label flip and noise injection—affect online AutoML learners in IoT networks and evaluates the effectiveness of adversarial training (AT) as a defense. Experiments on streaming-capable models (Hoeffding Tree, Leveraging Bagging, Adaptive Random Forest, Hoeffding Adaptive Tree, and Streaming Random Patches) show that AT-SRP achieves the highest F1-score (0.904) against label flip attacks, while AT-LB achieves the highest F1-score (0.933) against noise injection. Drift detection methods were also employed for rolling accuracy and prequential evaluation.

Empirical Evaluation of Data Poisoning Attacks in Supervised Learning

The paper evaluates two training‑time data poisoning attacks—label flipping and backdoor poisoning—on MNIST and Fashion‑MNIST using Logistic Regression, Linear SVM, and Random Forest classifiers. Label flipping degrades performance most for Logistic Regression and Linear SVM, while Random Forest remains relatively stable. Backdoor poisoning achieves near‑perfect attack success rates across all models while largely preserving clean‑test accuracy, highlighting the stealthy nature of targeted backdoors.
